My husband always tells me that I'm the best tasting woman he's ever had and I'm a total health nut. I don't eat any red meat, junk food, fast food, fried stuff, white flour, don't drink, don't smoke etc. etc. So, basically, you are what you eat. If you eat nasty, fatty stuff then its going to make a difference. I also almost always shower or wash the genital area if I'm short on time before any sexual contact.
